Looking for 1968 Buick Riviera back glass.... need to get current glass resealed and want a back up.

After making a few phone calls I have had no luck in finding a back glass for a 1968 Buick Riviera back glass. The seal on the current glass is leaking and I would like to get this fixed... unfortnately the possiblity that the glass can break during removal or re-installation is high. I was in hopes to find a back glass to have access to in case this were to happen otherwise my only option is to leave the seal leaking which is causing more damage to the upholstery.

go to car-part.com .there are several listed. a good glass shop should not have any trouble takeing yours out with the modern equipment. we used to remove them with piano wire .020 in size.with no trouble.
